I think the article overall is missing important sections describing the mesodermal layer in active organisms. Perhaps including references to articles such as this http://www.ncbi.nlm.nih.gov/pubmed/24088538 would better expand on the formation regulation of mesodermal organs. I feel like something as important is the mesodermal layer deserves more than 6 sections outlining its entire importance.
I am considering developing this page further as part of an educational assignment in Fall of 2013. If someone else is also working on this, please send me a message and let me know soon, so we donʼt duplicate initial efforts in page development. Josemags (talk) 00:24, 7 October 2013 (UTC)
The first couple of lines say when the mesoderm forms, but do not contain a definition ("The mesoderm is..."). Is it the set of cells that eventually become the muscle, blood, etc, as shown in the graphic? (22.214.171.124 17:36, 18 October 2007 (UTC))
Oppose merge. There is much more to say about these subjects, but it is harder for the articles njnj to expand when they are all combined. --Arcadian 18:48, 29 April 2006 (UTC)
Oppose merge. I agree with above statements.--Gmosaki 13:52, 14 May 2006 (UTC)
Isn't GI tract endoderm in origin?
- Yes. --David Iberri (talk) 23:46, 7 April 2007 (UTC)
- then why is it still on this page? --Sakredfire 05:45, 30 August 2007 (UTC)
The following text was removed as it does NOT seem hugely relevant to the main article:
Not all triploblastic animals have a coelom, like the simplest animals with organs that form from three tissue layers: flatworms. There are three different ways in which the mesoderm is found aligned with the ectoderm and these form a method of categorizing animals into three broad groupings.
- no coelom
- tissues and organs packed between gut and body wall
- Pseudocoelomates (blastocoelomat)
- false coelom
- unlined or partially lined body cavity between gut and body wall
- proper coelom
- lined cavity between gut and body wall
Maybe it can be revised and restored? Peter morrell 09:28, 24 February 2009 (UTC)
Not restricted to humans or vertebrates
Until I edited, the article was restricted to humans or vertebrates. I've edited the first para, and it's good as far as it goes. The whole article needs a rewrite. I'm tempted, but: I have a "to do" list of invertebrate phyla; doing mesoderm properly, i.e. showing comparisons and contrasts between higher bilaterian taxa, needs more zoology than I know. --Philcha (talk) 10:26, 10 March 2011 (UTC)
- It's still limited to vertebrates. Mesodermal formation on protostomes are entirely omitted. Petter Bøckman (talk) 12:01, 22 May 2017 (UTC)
Problem with Definition section
This sentence is broken, but I'm not sure what it was originally supposed to say:
- The paraxial mesoderm forms the somitomeres, which give rise to mesenchyme of the head and organize into somites in occipital and caudal segments. give, sclerotome (cartilage and bone), and dermatome (subcutaneous tissue of the skin).
